ATOMIZER.

Specification of Letters Patent.

Application filed June 28, 1913. Serial No. 776,291.

Patented June 2, 191 4.

pelling mechanism of motor-cars and motor vehicles, especially ofautomobiles and motor trucks. The novel device pertains to that type ofcleaning. devices in which a light cleansing fluid, such as a lightliquid hydrocarbon is used for removing dirt, dust and spent lubricant.

The novel apparatus is operated by means of fluid pressure and thecurrent produced thereby carries along the cleansing liquid' While someformer devices of this kind required a fluid pressure reservoir,containing for instance compressed'air, witha pressure in said reservoirof about 100 lbs. per square inch, the present cleaning device may be0perated with very little pressure and in case of necessity even byblowing with the mouth. This has been primarily attained by constructingthe apparatus on the principle of an atomizerfor the purpose of producing and diffusing a fine spray by means of which the cleansing of themachine partsis e'flected both mechanically and chemically. The novelcleaning device requiring but little force for its operation, may easilybe attached to a pneumatic tire of a motor vehicle or an automobilewherein more power is stored than is required. for this purpose. Thismakes the apparatus a great convenience because no fluid pressure tankneed be carried along while the driver of a motor vehicle always has anair pump to pump up the tire when required;

in order to render the invention entirely clear reference is had to theaccompanying drawing in which Figure 1 represents in side elevation anovel cleaning" device embodying in desirable form the presentimprovements and showing a connection with a tire, and a vessel for theeleansin fluid. Fig. 2 illustrates on an enlarged seeds, partly insection, the

operative parts of the device. Fig. 3 is a front end view of the deviceon an enlarged scale.

Similar characters of reference denote like parts in all thefigures.

In the drawing,in Fig. 1, a represents the novel cleaning device, 6, care flexible connect ons attached thereto, (Z is the vessel contamingthe light liquid hydrocarbon such as gasolene or kerosene, e is asectional part of a wheel showing a pneumatic tire I to the valve 9 ofwhich the flexible connection,

preferably the rubber hose, 1) is attached.

The construction of the operative parts of the apparatus is apparentfrom Figs. 2 and 3.

The novel cleaning device consists essentially of an air conduit Ithaving at its front end a screw thread if. An intermediary connectingmember or part i is provided in its top rear portion with a screw thread11 adapted to receive the threaded front end portion of the air conduith. A narrow air tube j with exteriorly threaded rear end portion 7' isattached to the interiorly threaded front endportion of the air conduith. The intermediary connecting member 2' has a slanting bottom portion1'. with interiorly threaded rear end portion i into which fits thefluid conduit 7a which is provided with an exteriorly threaded front endportion The front end portion of the connecting member '5 has aninteriorly threaded front end portion '1'. into which fits a relativelywide tube 1 by virtue of its exteriorly threaded rear end portion Z Thetube Z is "adapted to house the inn-row tube j'ofthe air conduit, asshown in Fig. 2. Thus a passage for the cleansing fluid is createdbetween'the tubes Z and j. The front end portion of the tube j issoldered or otherwise suitably secured to the front end por tion of thetube Z wherebyit is prevented that any cleansing fluid passes outbetween the front ends of the tubes Z and j. For the purpose ofrendering it possible to create and diffuse a fine spray of cleansingfluid and air, the inner tube j of the air conduit has formed near itsfront end a peculiarly shaped atomizer device. This device is formeddirectly in the tube j by means of a special tool which presses in twooppositely located small leaves or flaps m, m These are slantinglyformed in a forward direction and being practically semi-circular, touchwith their peripheral points as shown on an enlarged scale in Fig. 3. Byforcing in the two semi-circular flaps m, at two openings are created inthe tube j through which the cleansing fluid supplied by the tube 70 andpassing through the space between the tubes Z and j may enter said airtube j wherein it is co-mingled with the current of air and issued throuh the nozzle 71 in formof a fine, well difiuse spray. The front ends ofthe openings created in the tube 7' by the formation of the flaps m, mare straight, as shown in Fig. 2, and the cleansing fluid passes onlyalong the slanting surfaces of said flaps, giving it thus a forwarddirection.

In the described manner a finely diffused spray of cleansing fluid andair is produced by means of a device resembling in its operation theaction of an atomizer. It is evident that thequantity of cleansing fluidis proportional to the size of the openings near the flaps m, m locatedin the inner tube j and to the force of the current of air. In order toregulate the flow of both the supply of cleansing fluid and the supplyof air valves may be provided at the rear end of the device, if desired,or one valve alone may be provided in one or the other conduit if thisappears to be desirable for special application. In Fig. l of thedrawing the valve 0 is purposed to regulate the cleansing fluid and thevalve 7) the supply of air.

I claim as my invention:

1. An atomizer for spraying fluid comprising an outer tube for theliquid and an inner tube for the air both united in the front to closethe space between said tubes,

and an atomizing device in the front portion of the air tube composed oftwo semi-circular leaves formed by ressing in a portion of the wall ofthe air tube thus creating openings leadin from the liquid tube into theair tube, sai leaves touching with their peripheral ends, and slantinglyarranged in a forward direction.

2. An atomizer for spraying fiuid comrising an intermediary support, anair conings leading from the liquid tube into the air tube, said leavestouching with their peripheral ends, and slantingly arranged in aforward direction.

3. In an atomizer for spraying fluid, scparate conduits for the air andcleansing fluid, an intermediary support, and an atomizing device in thefront portion of the air tube composed of two semi-circularleaves formedby pressing in a portion of the wall ofthe air tube thus creatingopenings leading from the liquid tube into the air tube, said leavestouching with their peri heral ends, and slantingly arranged in a orwarddirection.

4. An atomizer for spraying liquidand air for cleansing motor vehiclescomprising an outer tube for the liquid and an inner tube for the airboth united in the front to close the space between said tubes, anatomizingdevice in the front POl'tlOItOf the air tube composed of twosemi-circular leaves formed by pressing in a portion of the wall of theair tube thus creating openings leading from the liquid tube-into theair tube, said leaves touching with their peripheral ends, andslantingly arranged in a forward direction, and means on the air tubefor connecting it with the pneumatic tire of the motor vehicle.
